The object ot our invention is to provide a bumper construction peculiarlyV adapted tor installation on the well known VVhippet tour or six cylinder' cars. n l

lt is our purpose in this connection, to provide a. bumper construction providing,` a 'pair' ot tubular spaced bumper elements with clamping devices for connecting them together in Aspaced relation near their ends and curved supports extending from the respective. clamp 'devices and inclined toward each y other and connected together, one ot saidsupports having an upwardly inclined 'member Figure 2 is a perspective View ot one ot thev i devices embodying` our bumper construction.

vFigure 3 is a detail sectional view taken on the line 3F?) ot-Figure 1 g andl i Figure 11 is a side elevation oi' bumper devices installed upon an automobile trame.

iIn the accompanyin y, we have used the reference numeral l() to indicate gen` vorally the rear portion ot a car body. '.lhc

o drawin .chassis et the. ca r has the side trame members 1Q, preferably in the .toi-m oi channel bars,

opening toward each other and having downwardly ends.

Our bumper construction is what is commonly called bumperettes or fquartcr bumpers used 'for rearbumpers; Each and inclined horns 14: at their rear bumper comprises a pair of tubular bumper elements 16 arranged in slightly spaced vertical relation. The bumper elements are provi ded at their ends with caps 18.

` For fastening the bumper. gether, we provide in the case ot each bumper element, two tasteningmeans one of which isk arranged near each end of the bumper element 16. Each fastening; device comprises a strip ot metal bent to form a rcentral upright portion 19 between the bumper elements 16.

From the portions 19, the metal is extended ne ot the members to-` I to the spare tire.

posite the inember 19,-is anV end portion 22 arranged adjacent to andparallel with thepork tion'19. At the end ot therinp,- 2O opposite the portion 19, is an end portion 2li .overlapping the ond 22 and arranged parallel therewith.

i Boltsl are extended through ythe member 19 andthe ends Q2 and 24E for supporting the y bumper elements on the car.k `We provide' in each instance, two supporting elements A and B. fllhesupporting element A has an end portion asat 25 mounted on the inner endo'tthe bolt 26 and curved therefrom laterally and outwardly and also toward the/car as shown at QSinFigurel. y

At the rear end ot theportion 28 there isa portion 29 which is straight and at the rea-r end thereof, is a portion@ inclined upivard- Y ly and torwardly with relation `to the car.

The bumper support B has an end portion 32 connected to thevouter bolt 526. 'lhe'bolts' 26 'l are provided withnuts f i away from the end32` toward the portion 28 and thon orwardlywith `relation tothe car and terininatingin a. straight portion pan vallel with the portionQQ. The portions 291 and 3S are fastened togetherby meansof a. bolt 10 and nut 4:2. l f l f Portions 38 andk 29 are provided near the end ot the portion 30 witha hole .torec-eive a holt d4. The portion Sdisprovid d with a hole to receive a bolt d6. The member or portion 30,1inclinos upwardly so as to followV grencrally speaking, the contour ot the horn 141'. perhzups best illustrated in Figure 2. K y

The bolts fle and lff are extended through the horn 1/1 andare secured in place by means n 1 un ot nuts There isthus provided a bumper sor Each quarter bumper may beshipped as a unit with all parts asesmbledtogether sothatf all that need vbe done to install such a quarter bumper on` the car,*is to drill two holes in` the .horn and install thebolts 44 andl. ,4

The supports A and B form a rigid con# struction and yet in the ordinary metal used,

there is such resiliency as tofgivesomc cushioning,` effect. Thesebumpers have a hunch some appearance and altord.v ample protection kto the tenders while altordingalso space be-- tween them for permitting convenient access 2 mariee Each quarter bumper has and gives the apl Centra portion, rings extendingh thereirorn around the respe'tive bumper elements and terminating in overlapl'iingi' `ends parallel with ant adjacent to the eentrai portion and bolts o:-
